--------------------------------------

             Summary: Move Kafka version to be generated in code by build 
(instead of in manifest)
                 Key: KAFKA-1901
                 URL: https://issues.apache.org/jira/browse/KAFKA-1901
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.8.2
            Reporter: Jason Rosenberg


With 0.8.2 (rc2), I've started seeing this warning in the logs of apps deployed 
to our staging (both server and client):

{code}
2015-01-23 00:55:25,273  WARN [async-message-sender-0] common.AppInfo$ - Can't 
read Kafka version from MANIFEST.MF. Possible cause: 
java.lang.NullPointerException
{code}

The issues is that in our deployment, apps are deployed with single 'shaded' 
jars (e.g. using the maven shade plugin).  This means the MANIFEST.MF file 
won't have a kafka version.  Instead, suggest the kafka build generate the 
proper version in code, as part of the build.
